[XPERIA X10 General] wildthing_san:
** There is currently no announcement as yet from SE/Docomo with regards to a 2.3.3 firmware **

** In the mean time you can try using the pre-rooted firmware and modify build.prop to pretend to be a SO-1B 2.1 phone... **

** ..if you still wish to access Docomo Market and download protected apps such as SP モードメール **

** (See 2nd post for more info on the modification.)

** But any software that needs 2.3.x firmware will think you phone is a 2.1.x phone, so you may want to make modifications and switch back and forth **

---- ****** Old info below ****** ----

** 2.01.b.0.19 Docomo firmware is out i.e. Dual touch**

** Root with Flashtool 0.2.4 **

** http://xdaforums.com/showthread.php?t=920746 **

** Legacy info, you can now just use Docomo's official 2.1 firmware and then root **

** i.e. http://xdaforums.com/showthread.php?t=834428 **

** To go back to Docomo firmware use values 1233-7397 for *.prop files **

You will need to subscribe to the ｉモード.net service.

[Can I use the ｉモード.net モバイルアプリ from Docomo?]

Not unless you have 2 docomo lines, its only designed to read email from you other number. (you can not read email from the docomo account assigned to the sim in the phone!)

[Which app do i use for ｉモード.net then?]

Try third party "iMoNi" from the market place.

[Is there a Docomo bill application?]

Try third party "My Docomo Checker"
